The Design of an Integrated Power Control Unit for Hybrid/Electric Vehicle
Sanghoon Kwak,Taehwan Chung,Gunsoo Kang,Jinhwan Jung 전력전자학회 2015 ICPE(ISPE)논문집 Vol.2015 No.6
Despite the rapid growth of green vehicle markets in recent years, its components including control units are still very expensive compared to those on the gasoline/diesel powered vehicle. In order to reduce costs and save more space on the vehicle, integration technology is required to develop. This paper proposes the development progress and optimization of integrated Power Control Unit of Hybrid/Electric vehicle.
A Method for Improving HEV Motor System Efficiency Considering Battery Voltage Variation
Bumsik Kim,Mushin Kwak,Taehwan Chung,Youngkook Lee,Jinhwan Jung 전력전자학회 2011 ICPE(ISPE)논문집 Vol.2011 No.5
Interior Permanent-magnet Synchronous Motors (IPMSMs) are suitable for Hybrid Electric Vehicle (HEV) due to their high efficiency and torque/power density. Since the torque of a PMSM is determined by the stator currents, stator current control is essential to the torque control. Also, the available torque of a PMSM is dependent on rotational speed and battery voltage (dc-link voltage of the inverter). In this paper, a new current reference generation method is proposed, which can improve the system efficiency with high control accuracy even when the battery voltage varies. The performance of the proposed method is verified by experimental results.
